SECTIONAL TRANSFER ROLLER.

Application filed January 19, 1927. Serial No. 162,058.

This invention relates to inking mechanism, especially adapted for newspaper printing machines. The principal objects of the invention are to provide a simple and convenient way of eliminating the inking of the plate cylinder throughout a width equal to the width of one page or a multiple thereof; to provide the inking mechanism with sectional means for transferring the ink from one part of the inking mechanism to the other, which can be removed in sections so that wherever desired, of course, the inling mechanism and the whole series of rolls beyond the transfer device can be left uninked, whenever it is desired to run a web through the press less than the full width of the press; also to provide `an improved form of adjusting the sectional rollers into proper relation to the adjacent rolls of the ink distributing mechanism, and especially to provide for the adjustment of the sectional rollers out away from the inking rolls with which they come in contact when transferring ink.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which Fig. 1 is an end elevation of the ink motion of a newspaper printing press, partly in section, showing a preferred embodiment of my invention applied thereto;

Fig. 2 is a side View on enlarged scale showing details of a preferred embodiment of the invention; A

i Fig. 3 is an end elevationof the same;

Fig. 1 is a side view of a part of the ink` ing mechanism showing it clear across the press; and

Fig. 5 is a plan, diagrammatic in form, to show the relationship of the transfer rollers to the printed product.`

j Frequently in newspaperwork, it is necessary to run a web vof 1, 2, o r 3 pages in width instead of a web of the full. width. lWhen that condition arises, it has beenv customaryheretofore 'to cut oft' the composition from the transferroller throughout a length of the roller equal to the width of the printing area that is not to be used.` This transfer roller is located between the ink fountain and the ink motion ordinarily. If one page in width is to be omitted, a quarter of the composition of the transfer roller is cut away. This leaves a three-page printing ,socket `holder 15.

area. Of course in cases where only one or two pages areto be printed, additional amounts of the compositionarevcut away. lhcse rollers that are cut away have to be carried in stock and whenever it is necessary to use them, they have to be transferred to the press and the necessary change made to put them on. This invention is designed to avoid this keeping in stoel; of any mutilated rollers and also to avoid the time required for applying them to the ink motion when a narrow web is to be printed.

Referring now to the drawings, I have shown a typical ink motion. rThe only thing` to be considered here is the method of transferring the ink from the .piek-up roll to the ink drum. It is to be understood, however, that this invention can be applied. at other points in the ink motion, but here it stops thetransfer of ink at a point near the fountain. For the purpose of securing the above mentioned results, I provide, instead of a single transfer roller, a number of these rollers equal to the number of pages in the maximum width web to be printed and each one has a body portion of a length equal to the width of one page. They are divided up so that alternate ones are placed on opposite sides of the ink drum and pick-up roll.

Having described the general nature of 'the invention, I will now refer to the drawings. On each side of the pick-up roll and located in bearings on' the frame of the ink.

motion, I provide a stationary shaft fastened in proper bearings on the side frames of the inking fountains. @n this shaft 1() are rigidly mounted a number of brackets 11, each one provided with two projections 12 opposite each other for receiving a pair of radial and opposite adjusting screws 13.

`Between the adjusting screws extends a projection lt which is an integral part of a This socket` holder is mounted to turn freely on the shaft 10. By

i adjusting the two screws 13 at each end of the shaft 10, the transfer roller 16 is adjusted circumferentially around the shaft 10. Forholding each end of the transfer .roller 16, I provide a socket 17 having a vthreaded stem 18 which` extends down into `the socket holder which is provided with a. passage therein for the screw 18. A .nut 19 is provided for adjusting the screw 18 up and dowi'. rigidly with respect to the shaft 10.

The shaft of the roller 16 is held in the socket 17 by a cover Q0 which constitutes the completion of the bearing and is held in place as usual by a screw 21. The same adjustment has to be made at both ends of each of the transfer rollers 16. This provides a universal adjustment by which the rollers may be adjusted against the ink drum or the pick-up roll as may be desired. The proper pressure against the two is provided for as the screws 18 are mounted substantiallytangent with respect to the pick-up roll and practically radially with respect to the lnk drum. The transfer rollers project in between the surface ofthe two. Therefore the adjlistment by the screws 18 will regulate the amount of pressure of the transfer rolls on the two surfaces with which they come in contact, the pick-up roll and the ink drum. The adjustment of the transfer rollers by means of the screws 13 is for the purpose of drawing the transfer rollers back out of Contact with eitherone, or both of the ink drum or pick-up roll. lVhen drawn back, the rollers 16, if desired, can he removed from their bearings by loosening up on the screws 21. I l It will be seen that if it is desired to eut otf'one or more pages in width of the plate cylinder'so as not to supply that portion thereof With ink, the proper transfer roller 16 is drawn bac-k out of contact with the piek-up roll by means of the screws 13 and no more. i-nk will be deposited on the ink drum throughout that area. The rest of the inking device will operate as usual. IVhen it is desired to return the transfer roller to inking position, it is simply adjusted back by the screws 13 and the original adjustment of the screws 18 does not have to be changed ordinarily. By placing the transfer rollers 16 alternately on opposite sides of the pick` up roll, the necessary space is provided at their ends for supporting and adjusting them and these adjusting devices are thus arranged far enough apart softhat the operator can get at them to perform the desired adjustments.

Although I have illustrated and described only a single form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the vart without departing from the scope of the invention asexpressed in the claims. Therefore,'I do not wish to be limited to all the details of construction herein shown and described, but what I do claim is:

1. In an inking device, the combination with the inking rolls and cylinders, of a set of rollers constituting the sole means'for transferring ink through one portion of the inking mechanism, said rollers being arranged in short lengths, arranged to supu ply ink in a continuous strip, across one of the rotary inkingmembers when in contact therewith and adapted to be brought into and out of cont-act with the rotary inkingr members of the inking mechanism so as to transfer the ink or not as luay be desired.
